This is it. I'd take the Wilder II version of Fury over Vitali. The one who beat Wlad too. I do agree he'd lost a bit by the time he fought Usyk.
Not relative to the 1980s or 1990s where big men flourished no. However in the 1950s they simply didn't contribute anything whatsoever to the division to the point you could easily avoid fighting them because they couldn't get a ranking. Liston in his entire career fought maybe one or two guy who would struggle to make cruiserweight Same with Marciano
